JimInVA Posted January 9, 2007 Share Posted January 9, 2007 For computer builds using the following items: - Mainboard: MSI K9NBPM2-FID (Memory Voltage Set @ 2.1V) - Processor: AMD Athlon64 X2 5200+ - Power Supply: ALLIED AL-B500E 500W - Initial Memory: CORSAIR TWIN2X2048-6400C4 (2GB-KIT) - Alternate Mem: CORSAIR TWIN2X1024A-6400 (1GB-KIT) In two different builds, each using the same model numbered items listed above, I had the following symptoms/findings: When using the 2GB-KITs in a Dual-Channel configuration, both systems would fail to initialize. When using the same 2GB-KITs in a Single-Channel configuration, both systems worked perfectly. In the same systems, using the 1GB-KIT [in place of the 2GB-KIT], both systems worked perfectly in either Dual-Channel or Single-Channel configurations. This mainboard's BIOS does not allow for memory setting adjustments other than voltage. There are four memory slots on this mainboard. I would prefer to use two "matched" 1GB modules for this 2GB Dual-Channel configuration to allow for future expansion. My question(s) - The TWIN2X2048-6400C4 is a Corsair "recommended" kit. Is this recommendation in error? If so, what should I be using instead? If it would be helpful, I would be willing to purchase a 2GB-KIT from another memory manufacturer to determine if such change would allow for proper operation. Would this be helpful in attempting to pursue a timely resolution to the problem I've experienced? Thank you! Jim [Note: I have emailed and telephoned with no response to either.
